SPRAY-NOZZLE.

Specification of Letters Patent.

Patented Feb. 8, 1921.

Application filed August 11, 1919. Serial No. 316,564.

To all whom it may concern Be it known that I, BARTON H. CorFnY, acitizen of the United States, and resident of New York city, in thecounty of New York and State of New York, have invented certain new anduseful Improvements in Spray-Nozzles, of which the following is aspecification.

My invention relates to improvements in spray nozzles and the object ofmy invention is to provide a simple and convenient spray nozzle in whichmay be attained a maximum eiiiciency in turning the water or otherliquid from a rectilinear to a rotary movement and a maximum passage wayto obviate the clogging of the device, combined with the ready removalof the spindle. (Ether objects will appear hereinafter.

The various features of novelty which characterize my invention arepointed out with particularity in the claims annexed to and forming partof this specification.

My invention will be more readily understood by reference to theaccompanying drawings, in which- Figure 1 is a sectional elevation of myimproved device,

Fig. 2 is a cross section of the same on the line 22 in Fig. 1

Fig. 3 is a sectional elevation of the case, and

Fig. 4. is a view of the vane spindle.

Similar characters refer to similar parts throughout the several views.

Referring to the drawings, 1 indicates a cylindrical casing having aninternally tapered mouth section 2 with a discharge orifice 2 andprovided with an internally screw threaded seat 3 adapted for attachmentto a pipe 3 through which water or other liquid is to be fed to thenozzle.

In the casing l I provide a cylindrical spindle 4 provided with aplurality of vanes or blades 6 each comprising a longitudinally disposedlug 7 forming a locking base section adapted to be seated in the sockets8 in the casing 1 and bent over intermediate its ends thereby merginginto a spirally disposed upper Section 6 arranged to produce maximumefficiency in turning the water from a rectilinear to a rotarydirection.

A pointed conical nose 9 is provided on the inner or base terminal ofthe spindle 4 to extend into the pipe 3 to serve to divert the water tothe passages between the vanes 6 and to minimize the impact of thewater.

The spindle terminates at its upper end below the tapered mouth section2 of the casing 1 to form a circulation chamber 2 adjacent the mouth 2The device is assembled by inserting the spindle 4 in the casing 1 withthe lugs 7 seated in their sockets 8, which properly position thespindle and to lock it against rotation, and the device is then screweddown upon the pipe 3 which will form a shoulder to bear against thevanes or blades 6 and hold the spindle 4 securely in position. By thisarrangement I prevent the casing being screwed on the pipe unless thespindle is in its correct position, and the parts are capable of beingreadily removed and taken apart for cleaning.

My device being thus assembled, the water or other fluid is admittedunder suitable pressure from the supply pipe 3 and is diverted by thepointed nose 9 to the passageways between the vanes 6 and a spiralrotary direction is imparted gradually by the upper spirally bentportions 6 of the vanes 6 from which the water is discharged into thechamber 2 where the direction of the current is further modified by thetapering walls of the mouth section 2 and is discharged from the mouth 2in a spiral spray formation, the maximum efficiency in turning the waterfrom a rectilinear to a rotary direction with a maximum passageway beingthus attained.

Having thus described my invention, what I claim is:

1. A spray nozzle comprising a casing, sockets herein adjacent its base,and a spindle having a conical inner nose and a plurality 9f vanes eachcomprising a longitudinal lug section adapted to be seated in one of thesaid sockets and a spirally disposed blade.

2. In a nozzle, the combination of a casing, a socket therein adjacentits base, and a spindle including a body section and a vane having alongitudinally disposed section provided with an integral lug adapted tobe seated in the socket in the casing and a spirally disposed wingsection.
